STARTER FOR INTERNAL-GOMBUSTION ENGINES.

Application filed March 3, 1910.. fierial No. 547,105.

Be a known that 1, climate I. SACK- at Delmar, in the county of Clinton and State of Iowa, have invented anew and gines', of which the following is a specificav This invention relates to that class of starting devices for internal combustion enis supplied to the working cylinder from a source independent-of the source which supplies the charge when the engine is in opera It is the object of the invention to pro.-, 'vide improved means for forming the initial charge, and for delivering the same to the engine cylinder in a measured quantity.

The invention also has for its object to provide a-starting device ofthe kind stated which can be readily applied to all existing forms of'internal combustion engines without modifying or altering the structure thereof, and also one which is simple in construction, easily operated, and highly eflieient in operation.

With these objects in view, the invention consists in a novel construction and arrangement of parts to be hereinaftervdescribed and claimed, reference being had'to the accompanying drawing, in which' Figure 1 is a vertical sectional view of the apparatus. 'Fig. 2 is a horizontal section of lteferring to the drawing, 5 denotes a tank containing a supply of gasolene. The gasoleneis under" moderate pressure, air being pumped into the tank until the desired pressure is obtained. A pump connection is shown at 6, and a pressure gage at 7. In

is entered by a pipe 9, said pipe entering the tank through the top thereof, and terminating within the tank in an upward bend 10.

open, and is locatedabove the gasolene level in the tank. Entering the pipe 9 sidewise, is a pipe 11 of considerably smaller diclose to the bottom of the tank, and also extending for a short distance into the pipe 9. The pipe 9 passes out of the tank 5, and

being mounted by means of brackets 13 on pressure.

the tank. The valve proper is a hollow plug '14" Working inthe hereof the casing 12.

The plug 14.' is mounted for turning movement inthe cas1ng'12, and has atone of'its ends a stem,.15passin inga handle'll'fitted'to its outer end. The

I casing 12 has an outlet; 18 whichlis connected by. a pipe .19 to the engine cylinder (not shown). the? plane of the outlet, the plug :14 has a port 20, which, when it registers with the-outlehplaces the same in complug.

On the casing 12 are stops 22erranged in the path of the handle 17, and.

determining the two positionsof the plug 14. The operation of the apparatus is as 1501-.

lows: The tank5 is partly filled with gaso lene, and then pumped up to the desired I To supply a combustible charge to the'engine, the valve lug 14 is turned so .as to open the pipe 9 lnto the'interior of said plug. As already described, in this position of the valve plug, the port 20 is out of re ister with the outlet 18. The valve plug eing in the position stated, a supply of .,air and gasolene vapor flows through the pipe 9 into the interior of the valve lug. The valve plug is then turned to shut o the pipe 9 from the interior of the plug, and toplace the port 20 into registering position with the outlet 18, whereupon the valve plug empties into'the engine cylinder, the charge being carried thereto by the pipe 19. The charge is fired in the engine cylinder by the ordinary ignition device of the engine. When the valve plug is turned as described to place the pipe .9 in communication with the interior of the lug, thecompressed air in the tank enters t e upperjend of the bend 10 of the 'saidpip e,and upon flowing. past the end of the pipe llwhich enters the pipe 9, produces suctioninsaid pipell, and an atomizing action is hnd,the gasolene issuingfrom the'pipe. 11, and passing into the. pipe 9 in the form'of. a fine spray, in which orm it'pass'es into the valve lug,

. On the upper end of the ent portion 10 ated by a handle 24 from the'outside of the tank, said handle passing through the top of the tank. The pur-poseof this valve is to regulate the amount of air entering the pipe, and thus obtain a pro erly proportioned mixture of air and gaso ene vapor, to make an explosive charge capable of being ignited by the ignition device of the engine.

The valve plug 14 will be so proportioned that the supply Will give the correct quantity of vapor to the engine cylinder, and as the inlet port 21 closes before the outlet port 20 opens, there is no danger of an eX- cessive charge passing to the engine cylinder. The size of the plug will vary according to the number of cylinders to be supplied. The flow of gasolene vapor into the valve plug ceases When the pressure in the valve plug and the tank equalize, so that there is no danger of an excessive amount of gasolene vapor passing into the valve plug.

After the initial charge has been ignited, the engine picks up from its own carbureter.

\Vhat is claimed is:

l. A starter for internal combustion engines comprising a tank containing liquid fuel under pressure, an outlet pipe from the tank having its inlet end located above the liquid level, a pipe extending into the liquid, and opening into the outlet pipe, a valve 'casing havingan inlet to which the aforesaid outlet pipe is connected, and-an outlet connected to the engine cylinder, and a hol- 10w valve Working in the casing, and having ports controlling the inlet and outlets of the casing.

2. A starter for internal combustion engines comprising atank containing liquid fuel under pressure, an outlet pipe from the tank having its inlet end located above the liquid level, a pipe extending into the liquid,

to open the inlet When the outlet is closed,-

and vice versa. v v 3. A starter for nternal combustion engines comprising a tank contalnmg liquid fuel under, pressure, an outlet pipe from the tank having a valve-controlled connection.

to the engine cylinder, and-said outlet pipe having its inlet end valve-controlled and located above the liquid level, and a pipe extending into the liquid, and opening into the outlet pipe.
